Introduction: High Voltage Sparks

Picture of High Voltage Sparks

By disassembling a disposable camera, we can use the flash circuit to create high voltage sparks. Warning: This project can generate a deadly current and without proper safety precautions, you will die. I take no responsibility for injury or death that may occur. There are further safety recommendations in the last step.

Step 1: Disassemble the Camera

Picture of Disassemble the Camera

Pry the camera open using a knife and brute force. You don't need to save anything aside from the flash circuit.

Step 2: Bridge the Resistor

Picture of Bridge the Resistor

Solder a bridge across the current limiting resistor. There may be more than one. Follow the traces between the leads and the capacitor to find them.

To create the bridge, solder the two ends of the resistor together. In some cases, it might be easier to remove the resistor and solder a wire in it's place. Make sure to use wire that can handle the current. I would use nothing smaller than 24 gauge.

Step 3: Test

Picture of Test

Insert the battery and press the charge button on the back of the PCB. You'll probably want to wear some sort of protection at this point.

Step 4: Bridge the Leads

Picture of Bridge the Leads

Use something conductive to bridge the two leads coming off the PCB. I recommend soldering some heavy gauge wire to the leads in order to have better control over where the current is applied. Once the leads are soldered, you might wish to add a switch and enclose it in some sort of nonconductive box.

In this picture, we ran the current through a soda can. It melted the aluminum and put holes in the can, causing liquid to shoot out.

Step 5: Warning and More Info

Be careful! The current coming from this circuit is extremely dangerous and possibly lethal. Do not touch the leads while the circuit is charged and always be sure to discharge the circuit with a piece of conductive metal before handling.

After you've had some fun with the circuit, you can add another capacitor in parallel with the first one to create higher current sparks. These can get dangerous very fast and should only be used while wearing ear protection and a welding mask.

This is a Computer Science House project.

A resistor limits current not voltage; so by bridging the current limiting resistor you did not increase the voltage.

Doctor90250 (author)2015-03-22

actually a lot of you are wrong, lol. by bridging the "current limiting resistors", your output voltage remains nearly the same, but the amperage is increased to a possibly lethal level, so be careful.

How. Lethal????????????????????????????????????????????????????????????????????????????????????????????????????????????????? show me the math

Pixeldude (author)2015-04-03

I touched the conductive metal and got shocked, but I'm still alive, although it hurt like crap.

hi there,
i'm a student of mechanical engineering, i'm doing my final year project on remodeling of Internal Combustion engine. i may not use the conventional CDI or magneto ignition system. for which i need a ignition circuit to genetare spark from a 12 volt , 5amps DC supply. all i have is bike igniton coil with spark plug and a 12volt DC supply , please design me a suitable circuit to generate spark with it !!
the below link contains the ignition coil and 12volt dc supply which i have right now!

will it be able to create plasma arc?????

nh7tr (author)2008-07-01

what a fool, it will not kill u it has incredibly low amperage(need atleast .36 to die) get it straite befor u go scarin the public.

Callum Snowden (author)nh7tr2011-01-31

No, you need as low as 5mA to kill you...

mythbusterma (author)nh7tr2009-10-06

i tested a camera capaciter and it outputs about 25 ma, enough to hurt like hell and i almost destroed my mutilmeter testing it

On one of those bug zappers (2000v), it fried my electrical meter. It sucks

rocketman221 (author)nh7tr2008-07-26

it is probably not deadly with one capacitor but put in 3 or 4 and it could be deadly

then again......it would stop your heart right? so in theory you could shock yourself again and defribulate yourself into beating again

3 would be deadly, at least according to my multimeter

Coffee bean (author)rocketman2212008-12-09

yep

Callum Snowden (author)nh7tr2009-02-26

It takes something around 60 Ma (milliamp) and over 50 volts to kill you, 30 Ma and you're badly shocked. Something on the lines of that anyway.

ParkerK (author)nh7tr2008-12-12

Still hurts like hell though!

ComradeLynx (author)2008-11-08

Bridge what leads? Capacitor leads or xenon tube or whatt!??

mythbusterma (author)ComradeLynx2009-10-06

RESISTOR

i got shocked with a 1.5 volt camera, it shocked me so bad i couldnt talk or breathe!!

realy!? ive made a taser glove that uses a 1.5 volt flash, im not sure who to test it on..... how bad did it hurt?

PRITY BAD!! like i said it shoked the breath out of me

I have been shocked twice by a camera flash. the first time i was in primary school, it knocked me backwards and gave me a blister the size of my thumb. 5 years later all I felt was a hum and a funny feeling thrugh my arm. the smaller u are, the worse it is... i think

evanwehrer (author)stick-692008-12-09

I got shocked changing a light bulb twice and it felt soooooo funny.

Coffee bean (author)evanwehrer2008-12-09

ac and dc seem to feel different dont they

mythbusterma (author)Coffee bean2009-10-06

ac actually relaxes your muscles dc tenses your muscles..... i think it might be the other way around

mythbusterma (author)rocketbat2009-10-06

voltage=pain amperage=damage

and btw ten bucks says its not 1.5 volts pry more like 300 v from the capacitor

bylerfamily (author)2009-05-23

WRONG.The capacitor is still charged for weeks after you take the battery.If you don't believe me,open up a disposable camera and you will see a black tube about 3/4 inch long.Place your fingers across those leads at the same time...

edwin1989 (author)bylerfamily2009-05-23

As you may have noticed that comment was made 3 years ago and if you read all of the other comments made since then you would see that I already knew that:p

bylerfamily (author)edwin19892009-05-24

Oh,didn't see the other comments.

skatepark13 (author)2009-02-03

yea i used 6 9 volt batteries to power it not a good idea it blew up and i had to go the the hospital to get the piece of metal removed from my eye so dont over power these things

mr.break_it (author)skatepark132009-03-31

whoa, good job. lol ADD much?,

illdoyourdrugs (author)2008-08-26

You people STILL don't get it. A TAZER shoots projectiles into the target and electrocutes through wire. A STUNGUN uses two metal prongs pressed up against the target to electrocute. Get it right its really getting annoying!

Wesley666 (author)illdoyourdrugs2008-12-24

People get it, they just aren't complete nerds and don't really care probably. LAZINESS

we get it its a comon misconception but get over it tazer is actualy just a brand name of the first one made its an acronim (dont know how to speel it) and the word evoled so no most things that create a powerful shock are refered to as a "tazer" so get over it youll hear it alot

but the point is your right

ParkerK (author)2008-12-12

Nice instructable! And yes people, be careful with disposable cameras. I once was messing around with one before I knew about the high amount of energy stored in there and the shock made me drop. Hurts like crazy too! :(

devicemodder (author)2008-11-21

I have actually gotten shocked. And believe me it doesn't feel good!:-)

Kryptonite (author)devicemodder2008-12-09

Ow, I've seen one of these discharged without the resistors being shorted, and I'm hell scared already!

edwin1989 (author)2007-12-17

lol when I made that comment a year ago I didn't know what a capacitor did, now I see you guys told me, but I already learned it at school haha! Don't get me wrong, I'm no newbie at this, I study physics at an university:) but it's weird I still get reminder emails because I left a comment here ages ago...

Coffee bean (author)edwin19892008-12-09

im in high school and they see teach light bulbs and batteries. it is kinda sad because i no people in my HONORS class could do better

illdoyourdrugs (author)2008-08-28

i messed up ONE letter. Get a life

Noodle93 (author)illdoyourdrugs2008-08-29

No, I just assumed that if you were correcting someone on their spelling you would at least care to check that yours was also correct. I love debating. Seriously, it's a good sport.

Coffee bean (author)Noodle932008-12-09

so do i but it isnt debating it is correcting.

samshoes (author)Noodle932008-09-27

I disagree. I define "sport" as a contest of athletic skill or strength. Debating, however, is an intellectual contest. I agree that debating is fun, but it is not a sport.

Noodle93 (author)samshoes2008-09-27

Sometimes you need to race to beat your opponent in debating. It's tough.

Archive555 (author)Noodle932008-08-30

Me too. And I agree with you, he should set an example by using correct spelling when telling others to correct theirs.

agent harmsy (author)Archive5552008-08-31

funny, 'cos he wasn't correcting spelling, he was correcting the name of the object. taser is spelt nothing like stungun, but they both use high voltage. he was removing the confusion

exactly right. Are people going insane or what ha ha ha? And its not like i use the word taser everyday. All I did was look at how someone else spelt it and they were wrong.

Berkin (author)illdoyourdrugs2008-10-07

Actually, other people spell it like that, too. YOU"RE NOT ALONE!!!
